The US Securities and Exchange Commission (SEC) has formally proposed rescinding its 2024 climate disclosure rules, shifting the issue out of the courts and back into the agency’s rulemaking process. The 30 May 2026 proposal opens a 60-day comment period and signals that the SEC is actively seeking to dismantle the regime, extending uncertainty for issuers and investors.
After withdrawing its defence of the rules in 2025, the SEC had effectively left their fate to the courts. The US Court of Appeals declined to resolve the issue, returning responsibility to the Commission. The new proposal is the agency’s definitive response, reasserting control but lengthening the path to any final outcome.
At the centre of the rollback is a broader redefinition of the SEC’s remit. The Commission argues that the 2024 rules exceed its statutory authority and impose costs that are not justified by their benefits.
“SEC disclosure obligations should comply with the Commission’s statutory authority, be guided by materiality as the North Star, avoid the practical effect of dictating corporate behaviour, and be imposed only when the expected benefits justify the likely costs and burdens,” said SEC Chairman Paul S. Atkins in a statement.
This emphasis on materiality reframes the debate. While the original rules tied climate reporting to financial materiality, they also required standardised disclosure. The SEC’s current position suggests that even structured requirements may overreach if they are seen to influence corporate decision making rather than purely inform investors. For companies, that shifts responsibility onto boards and management to determine and defend what is material.
The proposal sets up a renewed legal contest. Environmental and investor advocates have already indicated they will challenge any rescission.
“The SEC’s Climate Risk Disclosure Rule makes sure people have information that they need to make important financial decisions. We will vigorously oppose rolling back the rule, which would threaten the financial security of workers and retirees who have their life savings invested in the markets,” said Stephanie Jones, Senior Attorney for Environmental Defence Fund.
As with the original rules, any final decision is likely to face immediate litigation, prolonging regulatory volatility and delaying a settled outcome.
Large multinational companies already reporting under frameworks such as the EU Corporate Sustainability Reporting Directive are unlikely to unwind existing disclosures. Instead, they face continued divergence between US and international requirements, increasing complexity rather than reducing it.
US-focused mid-cap issuers may see fewer immediate compliance obligations, but investor scrutiny remains. Expectations are particularly embedded in sectors with clear exposure to physical or transition risks, including energy, transport, and data infrastructure.
This divergence widens the gap between formal regulation and market expectations. Without a federal baseline, comparability shifts from rulemaking to investor engagement and private frameworks. Asset managers may respond by intensifying direct engagement or leaning more heavily on international standards.
For investors, the immediate implication is reduced standardisation in US climate disclosure rather than reduced risk. In the absence of a federal framework, comparable data will increasingly come from a mix of company judgement and international standards. This places greater weight on direct engagement with portfolio companies, reliance on non-US reporting frameworks, and independent assessment of material climate risks.
Investors should expect uneven disclosure quality in the near term and plan for a more active role in shaping reporting expectations.
